Ziolite-Based Catalysts in Jet Fuel Reformation for Power and Energy Applications

Presented by Dr. Ivan C. Lee
Research Chemical Engineer
U.S. Army Research Laboratory (ARL)

Fuel reformation converts complex mixtures of heavy hydrocarbons in transportation fuels to hydrogen, carbon monoxide and other small hydrocarbons. This reformate gas is a potential gaseous fuel for auxiliary power units for military and commercial applications. Some investigators developed novel perovskite-based, ceria-based and mixed oxide catalysts to reform surrogates of jet fuel and gasoline. Despite some recent success of making hydrogen from sulfur containing jet fuel, there is a critical need to develop new catalysts for better coke resistance and for higher sulfur tolerance. This presentation will first introduce the concept of surrogate fuels for the understanding of reaction mechanism, and we will also review some recent jet fuel reforming catalyst development in the literature. In addition, we will discuss the use of zeolite for autothermal reformation of real jet fuels with high sulfur content.

About the Speaker:

Dr. Ivan Lee joined ARL as a research chemical engineer in December 2001 after receiving his Ph.D. degree in Chemical Engineering from University of Illinois at Urbana-Champaign where he received the Drickamer Research Fellowship. His expertise includes fuel reformation, fuel processing for fuel cell applications, fuel chemistry, nanomaterials, catalysis and surface science. Dr. Lee was born in Hong Kong, and he was studying biochemistry at the University of Hong Kong before he came to US in 1994. He completed his B.S. in chemical engineering at the University of California, Davis where he performed research studies in polymer thermodynamics. He then held a summer internship to study low-k dielectric materials at the IBM Almaden Research Center before going to graduate school. Dr. Lee was the recipient of Richard Glenn Award for the best paper presented in the Fuel Chemistry Division at the American Chemical Society National Conference in 2004.
